SEEDING-MACHI'NE.

SPECIFICATION forming part of Letters Patent No. 240,535, dated April 26, 1881. I Application filed March 8,1881. (Model) To all whom it may concern Be it known that I, HARRISON ()GBORN, of Richmond, in the county of Wayne and State of Indiana, have invented certain Improvements in Seeding-Machines and other Agri cultural Implements, of which the following is a specification.

My invention relates to certain improvements in agriculturalimplements whereby their fronts are supported and the weight and downward pressure removedfrom the necks of the team; also, devices whereby the frame may be made much lighter and broader, so as to hold it rigidly in place. A flexible removable adjustable tongue is also provided, whereby the side lurch of the tongue is greatly lessened or prevented and the weight of the tongue removed from the necks of the team, and the tongue readily attached or removed from the frame, as hereinafter fully described in the specification and claims. i

Figure l is a top plan. Fig. 2 is a side elevatiom, Fig. 3 is a side elevation of the rear end of the tongue. Fig. 4 is a top view of the same. Fig. 5 is a perspective view of the upper caster-plate. Fig. 6 is a longitudinal vertical section of the rear end of the tongue, and a cross-section of the frame-timbers to which the tongue is attached. Fig. 7 is a top-plan view of the rear end of the tongue as applied to the frame. Fig.8 is a front elevation of the standard thatretaius the rear end of the tongue, as shown in Figs. 6 and 7. Fig. 9 is a side elevation, and Fig. 10 is a rear elevation, of the caster.

A is the frame of the machine; B, the carrying-wheels; O, the tongue; D, the caster which supports the front of the frame. The upper plate, E, of the caster is attached centrally to the front of the frame, as seen in Figs. 1 and 2. The lower plate, F, of the caster has the horns F, for carrying-the wheel D, and also the stem G, which passes through the upper plate, E, and sleeve W attached thereto and held in position by means of a pin and washer, as seen at E, Fig. 2. The caster-frame F carries an anti-friction wheel, V. (Shown in Fig. 2.) This wheel rotates on the bearing'lug I and runs near the outer edge, on the under side of the upper caster-plate,'E, supports the weight above, and removes the friction fromthe'caa This bolt also passes through the double-tree,

and the upper plate of the caster which supports the double-tree, the bolt L acting as a pivot for thedouble-tree, as seen in Fig. 2. Thus it will be seen that thedouble-tree is firmly attached independently of the tongue.

The tongue is attached to the frame in such a manner as to make it flexible, detachable,

and adjustable, as follows: The-standard'or support D is attached centrally to the upper side of the front rail and receives the tongue between its vertical sides, which are provided with a series of holes for the adjustmentof the tongue, as seen in Fig. 2. A plan view with the standard in cross-section is shown in Fig. 4, where rubber or any other elastic washers, bulfers, or springs are provided to deadenthe lateral side lurch of the tongue against the team. The rear end of the tongue is supported in a bearing, E, attached to a cross-rail of the frame, as seen in Figs. 1 and 2.

A spring, 0, at the rear end of the tongue extends into the bearing or support E to prevent concussion when the caster or either of the rear wheels strikes or passes over an obstruction. This spring may be formed as an integral part of the tongue(see Fig. 3) or made and attached otherwise. The holes in the vertical sides of the standard D are to permit of the vertical adjustment of the front end of the tongue by means of thebolt S, to suit the height of the team and to remove the weight of the tongue from their necks.

' As a modification of my improvement, the spring 0 may be dispensed with and an aptifriction wheel or roller, N, applied near the rear end of the tongue, said roller movin gin aproper retainer, as seen in Figs. 6, 7, and 8. This modified tongue is held in place by a bolt, T, passing vertically through the support D, the tongue, the buffers, and into the front rail. of frame. Near the rear end of the tongue, at the sides, buffers or springs U are attached to pre- Vent side lurch of the tongue. The spring washers or buffers B, Fig. 7, regulate the elevation or depression of the front end of the tongue by being placed above or below the tongue, in connection with the retainer E.

The advantages of my construction are that the machine is perfectly balanced, the front part carried and supported by the caster, the downward pressure and weight removed from the necks of the team, and the side lurch of the tongue prevented by means of the spring-buffers, and the perfect adjustability of the ton gne to take even the weight of the tongue offthe.

necks of any height of team, and at the same time be readily attached to and detached from the frame. The tongue, being merely for guidingthemachine, maybe much lighter than with the old construction. The frame also may be much lighter, and yet stronger, by means of the great strength and firmness given to it by the diagonal braces attached thereto.

On account of the great facility with which the caster-wheel revolves upon its axis and turns upon its stem, and by reason of the sup port given to the front of the machine, and freedom from friction, attained by the use of the anti-friction pulley-wheel, I am enabled to support and sustain the weight of the front part of the machine and the tongue, and thus produce a machine that may be turned round readily and easily on a very small space of ground, easily moved forward and backward, and the injury to horses necks prevented that occurs when using the old style of machines. My machine is also free from other objections common to other machines made in (the usual manner.

claim therein as new and useful, and desire to secure by Letters Patent, is

1. The caster-saddle D, having the horizontal projecting lug I, supported at one end only, and'cast as an integral part thereof, or otherwise rigidly attached thereto, for the purposes and uses substantially as set forth.

2. The caster-saddle D. provided with the horizontal projecting lug I, supported at one end only, and cast as an integral part thereof, or otherwise rigidly attached thereto, in combination with the wheel V, for the purposes and in the manner herein set forth.

3. The caster-saddle, having the horizontal lug I, supported at one end only, and cast as an'integral part thereof, or otherwise rigidly attached thereto, and the wheel V, in combination with plate F, stem G, shell W, horns F, and wheel D, substantially as set forth.

4. Frame A, in combination with the caster, composed of the plate F, provided with lug I, horns F, and stem G, plate E, wheel D, and wheel V, for the purpose of supporting the front of the machine and tongue, substantially as set forth.

5. In combination, the double-tree M, attached to the plate E of the caster, and to the bracebars J J by means of the bolt L, substantially as set forth.

6. The brace-bars J J, arranged to pass diagonally forward from the side rails, A, and across bars A and front rails, A, to meetin front, in combination with double-tree M and plate E, said barsbeing rigidly attached to the frame A A A, substantially as set forth.

7. The combination and arrangement of-the herein-described caster, the pivoted, adjustable, detachable tongue 0, and spring 0, standard D, bearing E, buffers P P, and bolt S, as and for the purposes substantially as set forth.
